the tip. In order .to 'further assist in mixing within the chamber below the mixer an extension tube. 2T is in ade integral with the mixer and extends Well down into the tip so that Sonie of the gas and oxygen flows through the perforations 25 while another portion flows through the extension tube Z7, the two cofi'niugling after they pass the outlet of the exteneion tube. 1t will be nn dorstood that either of the pointe may he eaeily and quickly plat-.ed within the head by means of cooperating threads as shown so that they are interchangeable. One of the tips is used in the artt for' welding', \\'heroa.s, the other lip-iagaised for cutting. heating the metal it i# usual to use the auxiliary Supply ol' purrx oxygen. Howe-Yer, those parti! --lar-iea-tnrtns are well known in the art and afplirant1 invention lies in his Specific type oi' torch und his specific: mixing means` as it if' these 'features which permit him to use fuel gas.

Having desrrilied ,my invention, hat .l olahn as new and desire to protect hy Letters Patent, is
